Answer:
96π
Step-by-step explanation:

V=96π
The measure of < JKL = 25+25 = 50 degrees.
Angle JOK = 360 -230 = 130 degrees , (where O is the center of the circle)
< OLK = < OJK = 90 degrees ( tangent to a circle)
< LOK = < JOK = 180 - (90+65) = 180 - 155 = 25 degrees
The solution is: < JKL = 25 +25 = 50 degrees
-6(-3)=18, so that is true
-6+(-3)=-6-3=-9 so that is true
-6-(-3)=-6+3=-3 FALSE
-6 ÷ (-2)=2 so that is true
Answer is C
Answer:
Method A.
Step-by-step explanation:
For solving this question we need to find out the z-scores for both methods,
Since, the z-score formula is,

Where,
is mean,
is standard deviation,
Given,
For method A,


Thus, the z score for 34 is,

While, for method B,


Thus, the z score for 34 is,
,
Since, 
Hence, method A is preferred if the procedure must be completed within 34 minutes.
